This invention relates to power delivering attachments for commercialtractors, such as are used for driving hoisting drums and the like and aims, among other objects, to

provide improved power takeoff mechanism which can easily be made as an attachment and can be so arranged'that it derives its power through the tractor transmission gearing without requiring anyextra change 0 speed gears. ,Also, the "invention contemplates an improved traction wheel dISCOn:

necting means associated with one axle of the tractor, so that the tractor can drive a hoisting drum while it is standing still.

This application is a continuation in part of my application, Serial No; 115,868, filed June 14, 1926, and entitled Power delivering attachments for automobiles, trucks or tractors.' In the accompanying drawings- Fig. 1 is atopfplan view of a tractor having the preferred embodiment of power delivering attachment and associated, mechanisms applied thereto;

I Fig- -2 is a fragmentary, vertical sectional view on an enlarged scale, taken through the power delivering attachment; 7 A

Fig. 3 is a fragmentary horizontal section also on an enlarged scale of the rear end Of the tractor, the wheel being omitted; and

Fig.4 is a fragmentary view partly in section showing the tractor driving mechanism and a disconnecting clutch. 7

Referring particularly to the drawings,

thepreferred embodiment of the invention there shown,,is applied to a tractor of the McCormick-Deering type; that is to say, a tractor having a bull pinion shaft as 'a' part of its driving mechanism whether or not it ,40 is of the crawler or regular traction wheel type. An example of the type of tractor illustrated is shown in United States Patent NO. 1,559,617.

Herein, the improved power delivering attachment derives its power from the bull pinion shaft- '10- and is associated with the tractor brake wheel .or drum 11. The usual drum is modified by providing a recess or opening 12 in its outer face around the end 5 of the shaft and in the recess is a combined drivers seat.

dust cover for the end of the shaft and in ball bearing support 13 for the end of a stub shaft 14 aligned with the bull pinion shaft and having a supporting arm 15 extending forwardly from the rear axle housing to provide a support at the other end of the stub shaft.

The stub shaft is shown as having a power delivering sprocket 16 and a clutch collar 17 rotatably and slidably mounted on it, the collar having clutch teeth 18 cO-operating with clutch teeth 19 on the outer face. of the brake wheel 11, the arrangement being such thatthe sprocket can easily be connected to be driven by the bull pinion shaft and theusua-l brake 20 of the tractor may be used as a brake for the sprocket. The clutch shiftingyoke 21 is shown as being slidably mounted on a short shaft 22supported on the rear axle housing and may be shifted by an upstanding lever'28 (Fig. 2) accessible from the drivers seat.

In the present example, the power delivering attachment is utilized to drive a hoisting drum 24 (Fig. 1) supported on a special frame 25 above the forward end of the tractor, the frame being conveniently made of structural steel shapes extending forwardly and upwardly from the rear axle housings. The drum is preferably driven by a sprocket chain 26 trained over the sprocket l6 and a drum sprocket 27. Also the drum has a clutch (not shown) between it and the drum sprocket and this clutch is adapted to be controlled by a clutch control rod 28 to which is connected a lever 29 adjacent to the as having the usual drum brakes 30 also adapted to be controlled by a brake lever 31 near, the drivers seat.

To enable the power delivering attachment to function while the tractor is standing still,.it is necessary to disconnect the rear wheels from the tractor differential or the transmission gearing. In the present example, I employ a single split axle somewhat similar to that shown and claimed in my Patent 1, 469,002, granted September 25, 1923 and substantially identical with that shown in my copending application, SeztNo.

Further, the drum is shown enti'al gearing'infa tractor of-the typ e-dis--- closed in Figs; 1' to 3 and also a split-axle clutch like that shown in my'aforesaidco pending application, 'Ser. No. 933%, eiic'ept. that the clutch is on the left axle instead of the right a'Xle. Herein, the inner end of the 93,404, filed March 9, 1926; that is to say,

by a clutch shifting lever 32 arrangedYbehind the left axle housing 33, the yoke for I bull pinion shaft'in its dr vingmechanism,

the clutch being carried by a shitting'barB l:

slidable in housing. 35 secured. to the axle housing. Th s arrangement permits the axle clutch to be "placed entirely out 'ofthe way of the power delivering mechanismand also; avoids the necessityto disturb the housing for the rear right handaXleor tomake any changewhateveron that side of the tractor..

In Fig. 4 there is shown the usual differ-v 'right anle 36 is shown in the broken away part ofthediii'erential housing. Since this aide is the sameras'that shown in the aiore said Johnston patent it requires no further illustration. But 'theleft axle is made -'in itwo'parts 37 and 38,- the part3? having an integral clutch element 39' and the other'part [having a bearing within the clutchel'ement "39 :and a slidable clutch element 40 'co-oper ating with'the element 39 issplinedon said partfso as to beoperatedbya yoke'el on the shifting bar 34- as previously explained. In this illustrative example, the clutch is disengaged so -as to disconnect the rearwheels of the tractor-and thus make it stand idle while thepower delivering mechanism is be; ing drven by the bull pinion shaft 10. 7' I 'Inthe operationof 'the 'tract'or for hoist ing purposes, it will be understood that the rear wheels or crawlers, as'the case maybe,

are first disconnected-andthen the'clutch' collar 17 on thestub shaft lat is shifted to engage the brake wheeh Power is thus delivered to the hoisting drum through the sprocketichainjand the speed is controlled by the tractor. gear shittingwlever through :thdtransmission. I'Ihis avoidsthe necessity to employ any special power take-off trans- ;mission or speed changinggearing.

- Obviously, the present invention-is not re stricted to the particulan,embodiment' thereof herein 1 shown and described. Moreover,

' it is not indispensable that all'thegfeatures (of-the invention be used-conjointly, since they maybe employed advantageouslyin various combinations and -sub-co1'nbinations.-
